VehicleEnterEvent is thrown when a plugin adds a passenger to a vehicle

[Kowaman]

Is your feature request related to a problem?

When using Entity#addPassenger, the event that is thrown - VehicleEnterEvent should it be a vehicle. The same is done when a player manually enters a vehicle. If you want to cancel the event, there is no straightforward way to distinguish between these two causes.

Describe the solution you'd like.

Add getVehicleEnterCause to VehicleEnterEvent, similar to TeleportCause

Describe alternatives you've considered.

Cancelling the interact event instead, though it's a bit less clean of a workaround. A way to properly distinguish player vs plugin passenger adding would be ideal
